Predation of juvenile salmonids within California’s Sacramento–San Joaquin Delta (the Delta) has been identified as a contributing factor to low survival during out-migration through the system. Artificial lighting at night (ALAN) may contribute increased levels salmonid predation by attracting predators and prey, increasing predator reaction distance, boosting foraging success. To assess ALAN ...

Artificial light at night (ALAN) has been implicated in the global decline of insect populations. Causal mechanisms contributing to declines remain unclear, however. Here we examine causal factors which could link some declining terrestrial populations with ALAN. To do so, defined closest and furthest halves individual bushes according nearest source artificial light. We sampled leaves inverteb...

Knowledge of the night sky radiance over a large territory may be valuable informationto identify sites appropriate to astronomical observations or for assessing impacts ofartificial light at on ecosystems. Measuring can complex endeavourdepending desired temporal and spatial resolution. Similarly, modelling artificialnight multiple points represent significant amount ofcomputing time depending...

This article makes the case for addressing pedestrian visual diversity when planning artificial light public spaces at night, by drawing upon original findings from an exploratory study where twenty-one open-ended interviews were conducted with experts in fields of lighting, urban and health studies. Specifically, this provides (1) introduction concept diversity, defined as condition, capabilit...

BACKGROUND Overwork, fatigue, and sleep deprivation due to night duty are likely to be detrimental to the performance of medical residents and can consequently affect patient safety. OBJECTIVE The aim of this study was to determine the possibility of deterioration of cerebral function of sleep-deprived, fatigued residents using neuroimaging techniques. DESIGN Six medical residents were inst...

Human-centered design is a problem-solving approach that focuses on people first—their productivity, comfort, and user experience. A bicycle should be designed with pedals, seat, handlebars, brakes...
